Top Story: Dirty jobs

Imagine picking through a 55-gallon trash can to look for maggots and other insects on a decaying pig that has been there for two months.

Not a pretty sight - or smell. But that is similar to what forensic investigators often do to help solve murders.

It's that dirty job that attracted producers of the television show by the same name to Purdue University. The Purdue forensic entomology team's study of insects on decomposing pig carcasses will be featured on "Dirty Jobs" on Sunday (Nov. 28) at 9 p.m. (Eastern) on the Discovery Channel. The episode is titled "Bug Detective."
